Yea I really needed to put in some sort of tutorial but ran out of time, what got you stuck ?
1. Click the deck
2. Roll the dice
3. Select dice to keep
4. Reroll the other dice ( Select a dice in the middle or hit the bell )
5. Try to make a weapon
6. Enemy Turn (Hit the Bell to end turn)
7. Repeat until you win/lose
Hope this helps any others coming into the comments
